Yesterday I downloaded a different antenna simulation program - NEC4WIN95, from http://www.orionmicro.com/n4w95/n95page.html This one is a 30 day trial, but the registered version is certainly not free. I wonder how they compare. I used it successfully to simulate my 5MHz long wire (see http://www.dsergeant.btinternet.co.uk/fivemegs/fivemegs.htm). However when I tried to simulate my 136 antennas I came unstuck so perhaps Dick's program is better for this.
